6 Claims.

My invention relates to a new and useful improvement in a storm window construction and particularly that type in which a pair of independent sashes are used for filling the window opening. It is an object, of the present invention to provide a storm window construction in which a pair of slidable sashes which are duplicates of each other in size and construction may be utilized.

Another object is the provision in a storm window construction of a pair of slidable sashes, one positioned above the other, so arranged and constructed that when moved into operative relative position, they will automatically secure themselves tog ther in a manner which will permit easy removal and replacement of the same and yet retain them securely in position for use.

Another object of the invention is the provision in a storm window construction of an auxiliary frame inv which a pair of sashes are slidably mounted in such a manner as to prevent rattling, providing an effective seal and permitting easy and quick removal and replacement of the slidable sashes from the interior of the building.

Other objects will appear hereinafter.

It is recognized that various changes and modifications may be made in the detail of structure illustrated without departing from the invention and it is intendedthat such changes and variations shall be encompassed within the scope of the claims which form a part hereof.

Forming a part of this specification is-a drawing in which:

Fig. l is a front elevational view of the invention applied to a window;

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1, slightly enlarged; Fig. 3 is a sectional view taken on line 3-3 of Fig. l, slightly enlarged;

Fig. 4 is a fragmentary, sectional view showing the parts in swung apart relation;

Fig. 5 is a fragmentary view taken on line 5-5 v tion mounted in a window frame 9 built into a wall l0. Projecting inwardly from the window frame are stops II and I 2 which extend the length of the frame. Set into the opening I 3 of the frame is an auxiliary frame embodying the *side rails i4 and I5, the top rail l6 and the bottom rail IT. This auxiliary frame is permanently secured on the window frame 9 with the side rails, l4 and I5 contacting at their inner faces with the faces of the stops H and I2 and the upper rail l8 contacting at its inner face with the stop 18 which forms a part of the frame 3. This construction is such that a substantially leakproof mounting is provided. Projecting inwardly from each of the rails l4 and I5 is a tongue l9 which extends throughout the length of these rails I4 and I5. It will be noted, as clearly appears in Fig. 3, that the auxiliary frame lies, at its outer surface, flush with the outer surface of the window frame 9 and to all appearances, seems to form a part of the frame 9. Slidably mounted in the auxiliary frame is a pair of sashes 20 and 2| each embodying side rails 22 and 23, a top rail 24 and a bottom rail 25. The construction of each of these sashes isidentical and in the drawings, I have illustrated the lower sashprovided with a screen 26 and the upper sash with a pane of glass 21. Projecting upwardl from the upper rail 24 is a tongue 28. Formed in the lower face of the rail 25 is a groove 30. The construction of the lower. sash is the same so that the tongue 28 on the upper rail of the lower sash will engage in the groove 30. Projecting upwardly from the rail [1 is a tongue 3| which engages in the groove 30 formed in the lower rail 26 of the lower sash.

A flange 32 is formed on .the rail I6 and projects downwardly so as to overlie the tongue 28' of the rail 24 of the upper sash, Thisflange 32 is of sufficient width so as to overlie the tongue 28 of the rail 24 of the upper sash and still leave clearance, as clearly shown in Fig. 2, so that the combined sashes may be moved upwardl a slight distance sufficient to permit the tongue 3| to disengage from the groove 30 formed in the lower rail of the lower sash. The flanges or tongues 19 overlie the side rails of these sashes so that a substantially leak-proof connection is made.

Each of the sashes is. provided on its inner face at the side rails thereof with the outwardly projecting flange 33 which engages the inner face of the rails l4 and I5. An examination of Fig. 3, therefore, will indicate that the member l9 and the member 33 serve to form a double seal, thus preventingleakage of cold air through the mounting.

Mounted on one of the sashes is a plate 3 having the semi-circular end 35 to provide a hook. Mounted on the other sash in alignment with the plate 34 is a plate 36 having a hook-forming curing the sashes in fixed relation while, at the same time, permitting separation of the sashes from the inside when the sashes have been moved upwardly sufllciently for the tongue on the rail H to disengage from the groovein the lower sash rail. To remove the sashes, it would be but necessary to raise the windows which are customarily mounted in the frame and then force both of the sashes 20 and 2| upwardly until the flange 32 engaged the rail 24. When in this position, the

tongue 3| would beout of engagement with the groove 30 and the lower end of the lower'sash ,could be swung inwardly, these interlocking hooks serving as a sort of hinge. After the inward swinging has been effected a slight distance, the

l-hooks will automatically become. disengaged, whereupon the lower sash may be removed. The 1 upper sash may then he slid downwardly so that "it may also be removed when positioned in the 1 lower part of the frame.

I and i5 and the rails 22 and 23. In practical operation, it is preferred to leave a clearan of approximately one-eighth inch at each side. Consequently, if the sashes and frame are painted on these opposed faces, the likelihood of the sashes sticking together through the adhesion of Mounted on the inner face of the side rails of each of the sashes are resilient springs 39 in the 1 form of a loop which bear against theinner face jof a window sash 40 which is mounted in the ordinary window frame. These springs serve a two-fold function. They serve to retain the 1 tongues 33 pressed tightly against the inner face Iof the rails l4 and I5 and maintain the rails i pressed tightly against the tongues or flanges [9. This storm window construction may be used either in the winter or in the summer and when used in the summer time, the upper sash which carries the window pane would not be removed but only the lower sash and it would be substituted by the sash which I have illustrated in the drawing in which the screen 26 is mounted. The

the paint is reduced to a minimum.

As clearly shown in the drawing, the sashes are held against inward movement solely by the pressure of the springs 39. Should the outer surfaces of the auxiliary frame andthe outer surfaces of the rails of the sashes be painted while -assembled together, the sashes could easily and said flrst-namedframe and embodying oppositely usual practice is to use, in the summer time, the 3 structure as shown in Fig. 1, with a glass window above and a screen window below. Some individuals and, under certain occasions, all-indi viduals would prefer to have the screen sash at the top with the window-pane bearing sash at the bottom. With this type of construction, this may be done because of the close similarity of the sashes. In installing the sashes in the auxiliary frame, the upper sash is inserted first and moved upwardly to its proper position. The springs 39 will serve to retain the upper sash in position and prevent its slidingdown even when the lower sash is removed so that no difficulty is encountered in mounting the sashes in the auxiliary frame.- In this mounting operation, the upper 1 sash is moved upwardly beyond its normal posi- 1 tion. The lower sash is then placed in i position and moved upwardly to engage and interlock with the upper sashand then the combined structure is moved downwardly so that thetongue on the'rail l'l engages in the groove of the lower face and in this downward movement,

the two sashes move as a unit because they are interlocked together.

It will be noted that the tongue on the rail I'I is oi? less height than the tongue '28 on the sash'es disposed side rails, a top rail and a bottom rail lying with their outer faces substantially flush with the outer face of said first-named frame; an inwardly projecting flange at the outer surface and on the inner side of each of said side rails and said top rail; a sash slidably mounted in said auxiliary frame and comprising a pair of oppositely disposed sash side rails. a sash bottom rail and a sash top rail; an outwardly projecting flange on the outer edge at the inner face of each of said sash side rails overlying and contacting the side rails of said auxiliary frame, inwardly projecting flanges on the side rails of the auxiliary 7 frame overlying the sash side rails and in contact therewith; and resilient means for maintaining said side rails and said flanges in contact with each other.

2. A window construction of the class described adapted for mounting in a window frame, comprising: an auxiliary window frame mounted in said first-named frame and embodying oppositely disposed side rails, a top rail and a: bottom rail; and inwardly projecting flange at the outer surface and on the inner side of each of said side rails and said top rail; a sash slidably mounted in said auxiliary frame and comprising a pairof oppositely disposed sash side rails, a sash bottom rail and a sash top rail; an outwardly projecting flange on the outer edge at the inner face of each of said sash side rails overlying and contacting the side rails of said'auxiliary frame,

' inwardly projecting flanges on the side rails of so that the upward movement of the interlocked sashes, in order to clear the tongue on the rail i1, is reduced to a minimum;

.. Experience has shown that the various advanmay be very easily and quickly changed from one type to the other.

It will be noted that there may be a clearance at each side of the construction between the rails the auxiliary frame overlying the sash side rails and in contact therewith; and resilient means for maintaining said side rails and said flanges in contact with each other.
